RADIAL ROLLER BEARING Russian patent published in 2010 - IPC F16C19/22 F16C19/26 F16C33/34 

FIELD: machine building.

SUBSTANCE: radial roller bearing includes inner ring, outer ring, cylindrical rollers with chamfers, and separator. Each cylindrical roller is provided with chamfers the shape of which is formed with rotation of circular arc the chord of which is determined with allowable values of chamfer coordinates along outer diametre and edge of cylindrical roller around longitudinal axis of roller, and with ratio of coordinate values; at that, radius of circular arc is determined with geometrical equation R=(L_p/2-r₁)/sinα, where L_p/2 -half of the roller length, α=arctgr₂/r₁, r₁ - chamfer coordinate along outer surface of cylindrical roller, r₂ - chamfer coordinate along the edge of cylindrical roller.

EFFECT: increasing service life.
